Question

Volume is best given by ___________

(a) Product of mass and density

(b) Ratio of mass to density

(c) Addition of mass and density

(d) Subtraction of mass and density

The question was posed to me in unit test.

I'd like to ask this question from Centre of Gravity topic in chapter Centre of Gravity and Centroid of Engineering Mechanics

Answer 1

Correct choice is (b) Ratio of mass to density

The explanation: The density is the ration of the mass to the volume of the body. Thus arranging them and the volume is said to be a ratio of mass to density. This equation is generally used in the calculations of the centroid of the body or the centre of gravity.
